Hi Rickjb,
I set up the RAM-disk so that it backups the folder at every shutdown and restores at bootup. This works pretty well. You can also press a button to synchronize to disk on demand. I haven't dug deep enough in ImDisk that I use to find if there is a feature to periodically sync to disk at given time intervals or not, but that would of course be a nice feature.

During BOINC setup I simply point the entire BOINC data directory to be installed on the RAMDisk.

In case of a crash, yes I lose some data, but if last shutdown/sync to disk was long ago, BOINC will simply mark the WUs as "aborted by project" (since the WUs stored on disk were old) and download new ones. In results status, the other "lost WUs" will be marked as Detached.

Before creating a RAMDisk, I usually make sure that the system is stable by letting it run 24/7 WCG crunching. After that I create a RAMDisk.

Another option would of course be to attach a 2.5" or 3.5" HDD and put the BOINC data folder there. But HDDs are slow so that's also suboptimal.

A power outage will of course be bad (same as crash scenario above), but there's only one thing to do if you have frequent outages is to get a UPS for battery backup. Then you can connect it to the PC via USB and its software will then notice if the UPS loses power form the outlet and you can choose what you want for it to do. For instance, perform a clean Windows Shutdown (at which point your RAMDisk will sync to disk as well).

Let me just provide my two cents on why I started with RAMDisks.
I have killed probably three or four SSDs on PCs doing nothing but WCG crunching on those said machines 24/7. CPU didn't die, Motherboard didn't die, PSU didn't die etc, but SSDs POOF! I have a Kingston 1TB SATA SSD in a machine built in August 2020. That machine has Not been running RAMDisk and Remaining SSD life is reported as 65%! That's a lot of writes from WU crunching only. That machine has an AMD 2700X (16 threads). The more threads you have running in parallel, the more writes will take place. On my 2990WX 64-thread, before I installed a RAMDisk, it chewed up the lifespan of a 500GB M.2 in a few months.

So how do SSDs fail from writes? Well, in my cases I suddenly noticed the PC semi-locking up and then after a while locking up hard. You go "hmmm, is it the RAM, bad SATA cable, motherboard, PSU?" No, swap the SSD and PC runs fine again!

So, RAMDisk or HDD is the only thing I'm putting BOINC data folder on nowadays.

If you want to measure how many writes you get to your SSD, download HWInfo64 and there you can keep logging writes for a while and then extrapolate. I did, and it made me act Fast! ;)

Wow, that sums up everything anyone wanted to know about crunching and SSd's!!!!

I had installed an SSD on my Desktop in August 2020 and checking it on Crystal Disk info I noticed the writes to be in excess of 6000 Gb which prompted me to do some research.

I do have a normal drive on the desktop as well so maybe it would be a good idea to transfer the data file to HDD which may solve the excessive writes to SSD.

Thank you very much again for your very generous help and wonderful explanation. I am sure it will help others too if they were not aware of how much wear and tear is done by crunching to the SSD's

:) well . We are live :) Crunching data already :) so here we go : )

It was propably here somewhere but Im not much of edit guy :

Is there a easier way to set up :

Sometimes when it runs, GPU usage jumps really high then even moving mouse is laggy as hell . It doesnt do that when i crunch Einstein stuff ..

Like somewhere to set up use max 75 percent of capacity of gpu ?
